I will describe the major scientific motivation and outline design concept for a new 2 degree field, 1000 fibre multi-object spectroscopy facility for the WHT. WEAVE is expected to be completed by early 2017 and will be capable of addressing a wide range of Galactic and extra-Galactic goals, covering the redial velocity follow-up to the full depth of the Gaia astrometric catalogue, stellar abundances and chemical labelling in the Galactic halo, galaxy evolution from integral field studies and from the identification of the LOFAR source population, and Cosmology. The instrument is complex, but not necessarily challenging, and will provide a major resource for the whole ING community for the next decade.

Luminous high-redshift radio galaxies (HzRGs) are associated with the most massive known galaxies in the early Universe. These galaxies have the properties expected of the progenitors of dominant galaxies in rich clusters.
I shall describe the properties of HzRGs and demonstrate how they can be used to study the formation and evolution of galaxies and clusters. I shall also show how LOFAR, the new European radio telescope, can be used to extend these probes into the epoch of reionisation.
